Question

A person 5 ft. tall is standing near a building 30 ft. high. If the length of the person’s shadow is 3 ft., what is the length of the shadow of the building?(1 point)

Answer 1

By similar triangles (same sun rays), height/shadow = 5/3 = 30/x. So x = 30*(3/5) = 90/5 = 18 ft.

The building's shadow is 18 feet long.
